3.0.1 and 3.1.1 Security AdvisoryTuesday, Sep 18th, 2007
Summary ======= Bugzilla is a Web-based bug-tracking system used by a large number of software projects. The following security issue has been discovered in Bugzilla: * Even with account creation disabled, users can use the WebService to create an account. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Unauthorized Access Versions: 2.23.3 and above. Description: Bugzilla::WebService::User::offer_account_by_email does not check the "createemailregexp" parameter, and thus allows users to create accounts who would normally be denied account creation. The "emailregexp" parameter is still checked. If you do not have the SOAP::Lite Perl module installed on your Bugzilla system, your system is not vulnerable (because the Bugzilla WebService will not be enabled). References: https://bugzilla.mozilla.org/show_bug.cgi?id=395632 Vulnerability Solutions ======================= The fix for this issue is included in the releases. Upgrading to a release with the relevant fix will protect your installation from possible exploits of this issue.
